1.While shooting,photojournalists choose their shots in order to capture the picture that they want.For example,a photojournalist shooting a rich neighborhood may deliberately exclude the homeless people who wander around nearby from the picture in order to create a picture of undisturbed luxury.On the other hand,the same photojournalist may also shot photos that focus on the homeless,with the rich neighborhood in the background,to emphasize the class segregation in that part of the city.On their way back to the office,the photojournalist thinks about how to present the photos to make the impact that they wanted.They may decide which photos they were going to use and which photos they were going to cut out,or they may decide the order or positioning of the photos in a magazine spread.
2.A summary lead can help the reader understand what the journal piece they were reading was about.It can also help to organize the mass of information that the article contains into a short,easily understood passage.If a reader was short on time,they could read through the summary quickly and have a decent idea of what the article contained and decide if they wanted to come back to it later.However,having a summary lead runs the risk of encouraging the reader to read only the summary lead and disregard the rest of the article because they already know what it's going to say.
